I had the grand opportunity once to pee exactly on the Continental Divide, right on the stone marker. Had Wife1 check to see if anyone else was around.
I took the position, made sure of my sight picture, took a deep breath, let half my breath out, and let it go.
My aim was true and I was secure in the knowledge that exactly one half would end up in the Atlantic Ocean, and half in the Pacific.
A personal best.
